In Outlook, you also have to tell it that the SMTP server uses SSL, and (of
course) open port 465 in your firewall.

I also had to tell Outlook to perform POP authentication before SMTP to get
it to work.  Not sure why that was needed, but it's a simple setting to
enable so I didn't bother investigating.
